IMPROVEMENT IN FISH-BARS FOR RAILROAD-RAIL JOINTS.

Spemfication forming part of Letters Patent No. 171,7 [3, dated January4, 1876; application filed December 11, 1873.

To all whom it may concern:

Be it known that I, JAMES M. ATKINSON, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a certain new anduseful Improvement in Fish- Bars for Railroad-Rails and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and t0 theletters of reference marked thereon.

My invention relates to an improvement in fish-bars for railways; andconsists in a fishbar provided with a lug, which is formed by bendingone end of the bar and then twisting the same into the shape hereinaftershown and described.

In the accompanying drawings, which form part of my specification,Figure 1 is a side elevation of sections of two rails provided with myimprovement in fish-bars. Fig. 2 is a top view or plan of the same,representing a part of the rails and fish-bars broken away.

In the drawings, A A represent the rails of a railway placed injuxtaposition, B and B,

pawls are used for the purpose of preventing the screw-nuts D fromturning upon their bolts 0, and the recesses f and i are for the purposeof catching the screw-nuts in different positions on the bolts, asindicated in Fig. 1.

In the accompanying drawings two forms of lugs are represented on thefish-bar B, one of which is formed in one piece with the bar inaccordance with my invention, the other being constructed separatelytherefrom, according to the usual method.

The lug h, by my invention, is formed by bending the end of-the fish-barat right angles, and then twisting the bent portion so that it will beon a plane with the upper surface of the cross-ties, (indicated by thedotted lines I.)

The lug g is of ordinary construction, being formed separately from thefish-bar and secured thereto by rivets or welding; but in JAMEs M.ATKINSON.
